i turned the time to 2099 and for some reason all my drivers where out of date and i now have an unknown rpc virus apparently:S, also it poped up saying my windows wasnt real ,it didnt know it was still 2009, isnt it ment to be able to tell when its just the user changing the time?

If you are running Windows 7 RC1, you need to start over by reformatting your drive and reinstalling Windows 7 RC1. Changing the computer's clock will cause the RC1 to expire prematurely since it is a time-limited release.Carey Frisch

yeah but shouldnt it know tht the time is wrong, otherwise anyone who wants the windows 7 for free can just keep the year back.
